vocab quiz

Question 1

conduction

Answer 1

Heat flow due to the contact of two objects or within a solid object. (Example: metal spoon in hot tea cup)

Question 2

convection

Answer 2

Heat flow due to fluid movement such as water or air

Question 3

emissivity

Answer 3

How much electromagnetic energy is reflected and how much is absorbed by an object in the form of heat. Emissivity is very dependent on color. (Examples: Aluminum foil has a low emissivity because it reflects a majority of heat and a black surface has a high emissivity because it absorbs a lot of heat; a black shirt gets hotter than a white one in the sun.)

Question 4

insolation/solar radiation

Answer 4

The amount of solar radiation that reaches a given area

Question 5

insulator/insulation

Answer 5

A material that does not conduct heat very well and has a low thermal conductivity. (Examples: A good jacket, fiberglass insulation, a sleeping bag, anything with air trapped in it.)

Question 6

nonrenewable resource

Answer 6

A resource that is not replaceable after it has been used. (Examples: Fossil fuels such as oil or natural gas, iron ore.)

Question 7

radiation

Answer 7

Energy transferred through the movement of electromagnetic waves; heat transfer not requiring a medium. (Ex: Feeling the heat from a campfire without touching the fire itself)

Question 8

renewable resource

Answer 8

A resource that is inexhaustible or replaceable by new growth; limitless supply. (Example: Solar energy.)

Question 9

thermal conductivity

Answer 9

The property of a material that determines how well it conducts/transmits heat. (Examples: Metal generally has a high thermal conductivity, plastic generally has a low thermal conductivity.)

Question 10

conduction

Answer 10

Heat flow due to the contact of two objects or within a solid object.

Question 11

convection

Answer 11

Heat flow due to fluid movement such as water

Question 12

emissivity

Answer 12

A property of the surface of an object that determines how much electromagnetic energy is reflected and how much is absorbed by an object in the form of heat. Emissivity is very dependent on color. (Examples: Aluminum foil has a low emissivity because it reflects a majority of heat and a black surface has a high emissivity because it absorbs a lot of heat; a black shirt gets hotter than a white one in the sun.)

Question 13

insolation/solar radiation

Answer 13

The amount of power received on the Earth’s surface per unit area. (watts per square meter in the SI unit system)

Question 14

insulator/insulation

Answer 14

A material that does not conduct heat very well and has a low thermal conductivity. (Examples: A good jacket, fiberglass insulation, a sleeping bag, anything with air trapped in it.)

Question 15

nonrenewable resource

Answer 15

A resource that is not replaceable after it has been used. (Examples: Fossil fuels such as oil or natural gas, iron ore.)

Question 16

radiation

Answer 16

Energy transferred through the movement of electromagnetic waves; heat transfer not requiring a medium.

Question 17

renewable resource

Answer 17

A resource that is inexhaustible or replaceable by new growth; limitless supply. (Example: Solar energy.)

Question 18

thermal conductivity

Answer 18

The property of a material that determines how well it conducts/transmits heat. (Examples: Metal generally has a high thermal conductivity, plastic generally has a low thermal conductivity.)
